Answer:

True

Step-by-step explanation:

<u><em>Explanation</em></u>:-

The equation of the standard hyperbola is  

                         \frac{x^{2} }{a^{2} } - \frac{y^{2} }{b^{2} } =1

  •       Center is (0,0)
  • Hyperbola is symmetric with respective to both the axes, since if (x, y) is a point on the hyperbola, then (-x, y), (-x,-y), (x,-y) are also lie on the parabola.
  • The relation of between focus and transverse and conjugate axes c²=a²+b²
  • The transverse axis is along x-axis  
  • The conjugate axis  is along y-axis
  • The length of transverse axis is 2 a
  • The length of conjugate axis is 2 b
  • The foci is (±c,0) and the equation of foci is x=±a e)
  • The length of Latus rectum is \frac{2b^{2} }{a}

Rewrite the expression without the negative exponent. 2x^−4
romanna [79]

Answer:

\frac{2}{x^4}


Step-by-step explanation:

The expression is 2x^{-4}

<u>We use the rule of exponents shown below to change the original to </u><u>"positive"</u><u> exponent form:</u>

<u>a^-b=\frac{1}{a^b}</u>


<em>Now we can change the original expression given into positive exponent:</em>

2x^{-4}\\=\frac{2}{x^4}

The units pf the digits of a two digits numeral is 8 if the digits are reversed the new number is 18 greater than the oringal nu
ra1l [238]

complete question:

The sum of the digits of a two-digit numeral is 8. If the digits are reversed, the new number is 18 greater than the original number. How do you find the original numeral?

Answer:

The original number is 10a + b  = 10 × 3 + 5  = 35

Step-by-step explanation:

Let

the number = ab

a occupies the tens place while b occupies the unit place. Therefore,

10a + b

The sum of the digits of two-digits numeral

a + b = 8..........(i)

If the digits are reversed. The reverse digit will be 10b + a. The new number is 18 greater than the original number.

Therefore,

10b + a = 18 + 10a + b

10b - b + a - 10a = 18

9b - 9a = 18

divide both sides by 9

b - a = 2...............(ii)

a + b = 8..........(i)

b - a = 2...............(ii)

b = 2 + a from equation (ii)

Insert the value of b in equation (i)

a + (2 + a) = 8

2a + 2 = 8

2a = 6

a = 6/2

a = 3

Insert the value of a in equation(ii)

b - 3 = 2

b = 2 + 3

b = 5

The original number is 10a + b  = 10 × 3 + 5  = 35
